Go down to arrest men after bar brawl (4-3-3)
I believe the answer is:
free-for-all
'brawl' is the definition.
(I have seen 'disorganised brawl' mean 'free for all' so perhaps 'brawl' could also mean 'free for all')
'go down to arrest men after bar' is the wordplay.
I cannot quite understand how this works, but
'to' could be 'for' and 'for' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for free-for-all that I've seen before include "Disorganised event" , "Public brawl" .)
